Chapter 1172: Triple Spiritual Master

"Come on."

Yun Yi's momentum was shaken, and the Nine Extreme Sword pointed at the robbery cloud, with a strong expectation in his eyes. At this time, Cai Qingyuan was hiding underground and could not come out, and Yun Yi could not do anything to him. Moreover, five heavenly tribulations had already descended, and even he could not control the remaining four heavenly tribulations.

Therefore, at this time, he had no energy to care about Cai Qingyuan's life or death, and he had to concentrate on overcoming the tribulation.

Boom!

Boom!

Boom!

At this moment, the robbery cloud in the sky trembled violently, and three robbery thunders fell in succession, almost without order, and then bombarded Yun Yi at the same time.

Faced with such a terrible force, Yun Yi could not resist it and was instantly bombarded into the ground.

"It's great, come again."

Not long after, Yun Yi jumped out of the deep pit on the ground and let out a thunderous long roar at the robbery cloud.

After being bombarded by three robbery thunders in a row, his clothes were also a little damaged, but his aura did not decrease but increased, and he also gained a lot of benefits.

This thunderbolt is absolutely fatal to others, but it is a great tonic for Yun Yi. The moment the three thunderbolts hit him, they were refined by the nine lotus platforms and directly transformed into the purest power, becoming a part of his body.

Buzz!

As if sensing Yun Yi's provocation, the space shook violently, and then six thunder dragons poked their heads out of the calamity cloud, six pairs of eyes with a destructive aura stared at Yun Yi.

These six thunder dragons represent the will of heaven and earth. How could they let Yun Yi go easily after being provoked by Yun Yi? Then, the six thunder dragons merged into one, forming a huge thunder dragon that drilled out of the calamity cloud, opened its bloody mouth, and pounced on Yun Yi.

Its appearance seemed to have drained the power of the calamity cloud. After it descended, the color of the calamity cloud also faded a lot.

"This is enough."

Yun Yi's eyes lit up, and this is what he was waiting for.

You know, his Nine Extreme Sword has reached the edge of promotion, and it needs to be integrated with more powerful materials to advance.

The Zun-level war weapon is extremely tough. Not only is the material used to refine it extremely precious, but it also contains the power of heaven and earth. Even his Red Lotus Karma Fire cannot refine it again. He needs a strong power to refine the Zun-level war weapon.

However, although the first eight heavenly tribulations were powerful, they could not meet his requirements.

This ninth tribulation thunder fused the power of six thunder dragons. In terms of power, it was stronger than the previous eight combined. It was enough to refine the Zun-level war weapon.

As he said that, he threw the Zun-level war weapon he got from Cai Qingyuan directly into the mouth of the thunder dragon. Under the bombardment of this violent power, it was completely refined without resisting for long and melted into a ball of colorful liquid.

"Nine Extreme Sword, it's your turn."

As soon as Yun Yi finished speaking, the Nine Extreme Sword seemed to understand what he meant. The sword body made a series of buzzing sounds and flew directly from Yun Yi's hand and drilled into the mouth of the thunder dragon.

The colorful liquid seemed to sense the existence of the Nine Extreme Sword that day, and immediately gathered towards it. In a short moment, it completely merged into the Nine Extreme Sword, making the sword body fatter.

At this time, the thunder power around it also found an outlet, and continued to bombard the Nine Extreme Sword, like countless hammers, slowly knocking down its body.

Soon, the Nine Extreme Sword returned to its original appearance.

However, at this time, the Nine Extreme Sword suddenly made a buzzing sound, and a green dragon shadow floated out of the Nine Extreme Sword and began to absorb the thunder power around it to strengthen itself.

"What is this?"

Yun Yi raised his eyebrows. He didn't expect that this fusion of the Zun-level war soldier would completely stimulate the dragon bone that had been fused before, and after absorbing the thunder power containing the power of heaven and earth, it also began to transform.

Slowly, its color gradually changed from the previous green to light gold, and then from light gold to pure gold. From a distance, it looked like a real dragon.

Yin!

Suddenly, the golden dragon seemed to have absorbed enough power, and let out a loud dragon roar, then plunged into the Nine Extreme Sword.

The next moment, a dragon-shaped pattern slowly emerged on the mirror-like sword body, and the aura emanating from it suddenly increased, instantly breaking through the shackles and advancing to the level of a Venerable-level warrior.

"It's done."

Yun Yi's eyes lit up. The Nine Extreme Sword's advancement not only reached the level of a Venerable-level warrior as he wished, but also caused the dragon bones in it to transform and form a true dragon form.

Although the Nine Extreme Sword had just advanced to the ranks of Venerable-level warriors at this time, its power was close to that of a Venerable-level top-level warrior. The most important thing was that the appearance of the true dragon form increased its potential, laying a solid foundation for its future advancement to a Saint Soldier or even an Imperial Soldier.

However, refining a Venerable-level warrior and recasting the Nine Extreme Sword only consumed part of the power of the ninth thunderbolt, and the remaining power was all bombarded on Yun Yi.

The nine lotus platforms in Yun Yi's body immediately vibrated as the thunderbolt approached. Even so, it took a full quarter of an hour to absorb all the power and transform it into a huge amount of spiritual power to be injected into Yun Yi's Dantian.

Almost in an instant, the bottleneck blocking Yun Yi was broken, and his aura also soared rapidly at this moment.

In just a short moment, Yun Yi's cultivation level broke through from the ninth level of the Spiritual Emperor to the first level of the Spiritual Lord. His whole body was filled with powerful power, which was more than ten times higher than the Spiritual Emperor.

At the same time, part of the power was absorbed by the nine lotus platforms. Not long after, a brown lotus quietly bloomed on the lotus platform.

"Innate earth spirit body?"

After seeing the lotus, Yun Yi immediately felt the strong earth spirit power coming towards him. Without thinking, he knew that this was his sixth spirit body, the innate earth spirit body.

With this spirit body, Cai Qingyuan would not be able to escape his pursuit even if he wanted to continue hiding underground.

However, before he had time to be happy, a roar came from his body again, and then his cultivation broke through again, reaching the second level of the spirit master, with only a few breaths in between.

But after breaking through the second level of the spirit master, the growth rate of his breath still showed no signs of slowing down.

About a minute later, Yun Yi's breath reached its peak, and finally his cultivation broke through again, successfully breaking through to the third level of the spirit master. Until this time, the power contained in the heavenly tribulation was completely consumed by Yun Yi.

The tribulation cloud in the sky also completed its mission and soon disappeared without a trace.

Buzz!

At this moment, the Jiuji Sword seemed to have sensed Yun Yi's breakthrough and immediately came to Yun Yi's side. The sword body trembled slightly, as if congratulating Yun Yi on his breakthrough, full of spirituality.
